W tlorney Patented Mar. 18, 1930 JOHN SGI-ILEINZER, or RoonEs'rER,uriwxonx TOOL FOR REMOVING cars FROM JARS 1 Application filed. April 6,1928. Serial No. 267,971.

The object of this invention is to provide a new and improved wrench orhandle for removing the caps from glass jars, etc.

Another object of the invention is to make the wrench of sheet metal andmake it so that it will fit two different sizes of caps.

Another object is to make the wrench with a central disc and providegripping fingers or lugs on the rim of the disc that extend both up anddown from the central disc which lugs interchangeably serve as grippingfingers to grip the cap, or as a handle by which the wrench may be moreconveniently turned. These and other objects of the invention will befully illustrated in the drawings, de scribed in the specification andpointed out in the claims at the end thereof.

In the drawings: 7 v

Figure 1 is a perspective view of the glass jar with the wrenchsuspended above it ready to engage with the cap on the jar.

Figure 2 is a side elevation of the jar with the wrench in position onthe cap. 7

Figure 8 is a side elevation of the wrench in which one set of fingersare made corrugated so as to form a mutilated thread by which they maybe screwed into engagement with the cap. The other set of fingers aremade eccentric to the rim so that on one side so they will present anedge to the cap which is better adapted to engage the cap.

Figure 4 is a detail perspective view of a modified form of one of thegripping fingers of the wrench.

Figure 5 is another detail perspective view of a modified form of one ofthe gripping fingers of the wrench.

' like reference numerals In the drawings indicate like parts.

In the drawings reference numeral 1 indicates a glass jar having a metalcap 2 thereon which jar and cap is similar to what is ordinarily used indispensing mustard, jelly, peanut butter,.etc. 8 indicates the wrenchhaving a disc in the center on the rim of which are formed three radialextensions 4, 4, 4 on the outer end of which are formed upturned fingers5, 5. Also formed on" the edge of the disc of the wrench are threeclownwardly extending fingers 6, 6, 6. The fingers 6, 6,6 are spaced'apart1ona smaller circle having a shorter diameter and the fingers 5,5, 5 are spaced apart on a larger circle having a longer diameter. Thewrench is formed of a single sheet of metal in which the six fingers arestamped out integral therewith, the fingers 5, 5, 5being turned up andthe fingers 6, 6, 6 being turned down. The fingers 6,6, 6 .are used toengage a cap of small diameter and the fingers 5, 5,, 5 are used toengage a cap of larger diameter. The Wrench is used by'simply forcingthe fingers down over the sides of the cap until the disk of the wrenchrests on'top of the cap. The operator'will then press the lowerfingers'in against the cap and will turn the wrench, using the upwardlyextending fingers as handles by which to force the turn'ingof thewrench, and all 01": this can be done with one hand.

Ordinarily the downwardly extending fingers will engage the cap firmlyenough to hold it to force the turning ofthe cap without pressing thefingers of the wrench together with the fingers of the hand. This is dueto 75. the fa'ctthat the caps of jars'are ordinarily provided withabeaded rim which extends outwardly from the glass jar and which willcause the gripping fingers to spring out thus causing the wrench tomoresecurely engage the cap, and hold it in engagement therewith withyielding pressure. 1 By turning the cap and wrench on the jar, the capcan easily and quickly be removed from the jar. V In Figure 3 I haveshown one set of the grippin'g fingers 8, 8, 8 corrugated, thecorrugations forming a mutilated thread which engages the beaded edge ofthe cap 'andjserves to draw the wrench down firmly on the cap' 9 i andhold the wrench firmly in engagement with the cap so that thecap may bepositively turned thereby.

I have also shown the upwardly extending fingers 9, 9, 9 formed slightlyeccentric to a V tangent to the rim atthe point where the fingers areplaced. With the fingers formedin thisway the forward edge tends to cutinto the cap or the beaded edge thereof thus making a more positiveengagement therewith by which to' force the turning of the cap on'the'jar and secure'the removal thereof. I I I In Figure I have illustratedanother'modifiedform of the gripping fingers which is made by con'cavingthe outside of the fingers as illustrated so that a curved convexsurface is'pre'sented to the capwhen the'fipgers'coine in'contacttherewith.
